Hi@William180409, Welcome to the HP Support Community!
I assure you I will try my best to get this sorted.
In order that I may provide you with an accurate solution, I will need a few more details.
- Have you checked with an external mouse?
- Have you made any software or hardware changes on the computer?
While you respond to that, I recommend you perform a system restore on the computer back to the date when the touchpad was working fine.
Follow the steps in the below article to perform a system restore.
